Shumshu (Russian: Шумшу, romanized: Shumshu; Japanese: 占守島, romanized: Shumushu-tō; Ainu: スㇺス (reconstruction), lit. 'good island') is the easternmost and second-northernmost island of the Kuril Islands chain, which divides the Sea of Okhotsk from the northwest Pacific Ocean. The name of the island is derived from the Ainu language, meaning "good island". It is separated from Paramushir by the very narrow Second Kuril Strait in the northeast 2.5 kilometres (1.6 mi), and its northern tip is 11 kilometres (6.8 mi), from Cape Lopatka at the southern tip of the Kamchatka Peninsula. The island has a seasonal population of around 100 inhabitants.
